Chemistry - STEREO ISOMERISM Question with Solution | TestHub

(A) cis- and trans-2-butene are geometrical (cis-trans) isomers - stereoisomers that are not mirror images, i.e. diastereomers.

(B) The two Fischer projections of butane-2,3-diol differ at only one of the two stereocentres (one is the meso form, the other is the (2R,3R)/(2S,3S) form) - diastereomers.

(C) cis- and trans-1,2-dimethylcyclohexane differ at one of the two stereocentres - diastereomers.

(D) The two Fischer projections of 3-chloro-2-fluorobutane differ at only one of the two stereocentres - diastereomers.
